SEAFDEC, during the past decades, accumulated a variety of fisheries data such as regional fishery statistics obtained from the national statistics of the ASEAN Member States (AMSs) and information generated from several SEAFDEC programs and projects. SEAFDEC then integrated and analyzed these data and information in The Southeast Asian State of Fisheries and Aquaculture or SEASOFIA to support the sustainable fisheries development and management in the region. SEASOFIA is published with the aim to provide better understanding on the status and trends of fisheries and aquaculture of the region. This publication also aims to raise awareness and preparedness, and enhance the capacity of the AMSs to respond to issues and challenges in fisheries.
